compare_drapes
Compare up to 12 warp angles, sequentially, at one fixed seed and cloth configuration.
When omitted, seed is suggested once for the first angle. Results rank by
coverage descending, then percentage above lock ascending, then maximum
shear ascending. This is a stated comparison rule, not a global optimum.
Runs use the requested/preset pitch, never a hidden coarse approximation.
Export the chosen result promptly: backend result IDs are temporary.

create_layout
Start covering one surface with multiple pieces of the same ply/fabric.
This is not a laminate stack. overlap is mm; supplied seeds are laid first
and additional pieces fill remaining ground, up to max_pieces. Poll the
returned job_id with get_job(kind='layout'); export with layout=true.

create_workspace
Create a private two-hour workspace and return its ID and CAD upload page.
Start here before loading a sample or importing a user's CAD part.
The ID and upload/download links grant access; do not publish them.

Output schema
{'type': 'object', 'title': 'create_workspaceDictOutput', 'additionalProperties': True}
export_pattern

Output schema
{'type': 'object', 'title': 'export_patternDictOutput', 'additionalProperties': True}
get_job
Poll STEP import or multi-piece layout; retry after a short delay while done=false.
STEP completion returns a step_id and at most 20 basic face descriptions;
use list_faces for geometric descriptions and pagination. Layout completion
returns compact per-piece statistics and a layout_id for export_pattern.

import_part
Import a file already uploaded to this workspace. Get upload_id from list_uploads. STEP/STP returns a job to poll with get_job(kind='step'), then inspect and select faces.

list_faces
Inspect STEP face IDs, areas, bounds, centroids, neighbours and planar mesh normals.
This requires the MCP face-metadata endpoint in the configured backend.
Centroids/bounds describe the tessellation; do not assume a closed solid's
entire skin is the intended draping surface. Ask for explicit face IDs
when the intended surface cannot be identified from this information.

run_drape
Drape one fabric at one warp angle (degrees); return statistics and an exportable result_id.
Omitted seed is suggested on the surface. Omitted pitch/lock_angle use the
fabric preset, including its UD spread/compression settings. pitch/offset
are mm; hole_area is mm² (null bridges holes). The API may increase pitch
to bound the grid; pitch_used reports the actual resolution. Kinematic
shear/locking statistics are not a structural strength calculation.
